HOSE-CUUPLING.

Specification of Letters'Patent.

Patented July 2, 1912.

Application filed September 12, 1911. Serial No. 648,873.

which the following is a specification, refer-. the accompanyingence being had therein to drawing.

This invention relates to hose couplers or pipe couplers and has for its object the production of a simple and eflicient device which may be cheaply manufactured.

Another object of this invention is the production of a hose coupler which may be placed in position, and will not have a tendency to unscrew from the pipeline or hose line while being tightened together. With these and other objects in view this invention consists of certain novel construct-ions, combinations, and arrangements of parts as will be hereinafter fully described and claimed. I

In the drawings: Figure 1 is a side elevation of the hose coupler. Fig. 2 is a longitudinal sectionthereof. Fig, 3 is a section taken on line 3-3 of Fig. 2. Fig. 4 is a fragmentary plan view of the primary section of the hose coupler.

Referring to the accompanying drawings by numerals 1 designates the primary section which is preferably threaded at its outer end as at 2 and is provided with a collar 3 which collar may be primary member 1 by welding or in any other desired manner. The inner end of the primary section 1 of the hose coupler is enlarged as at 4 and said enlarged portion is provided at its inner end with an A lug 6 is formed upon the outer face of the enlarged portion 4 and extends from the flange 5. The lug 6 is provided with a beveled outer face for facilitating the placing of the lug within one of the sockets 16. Owing to this bevintegral. collar 5.

cled face, the lug 6 will be of less height at" its outer end than at its inner end.

A binding collar 7 is placed upon the primary section 1 and is ositioned between the flanges 3 and 5. This collar 7 is -provided with a reduced the body portion of the collar 7 is provided with a plurality of apertures 9 into which may be inserted a rod or tool for rotating the collar 7 upon the primary section 1.

The auxiliary section 10 of the coupler com secured to the -iary section 10 thereby threaded portion 8 and a reduced portion 11 which is threaded at its outer end as at 12 for engaging the pipe or hose line similar to the threaded port-ion 2 of the primary section 1, and said auxiliary section 10 of the hose coupling is provided with an enlarged portion 13 at its inner end. provided with a portion 14 which is slightly larger than the portion 11, and slightly smaller than the portion 13. The auxiliary section is provided upon its inner face is adapted to receive prises with a socket 15 wh1ch the forwardly extending portion 4: of the primary section 1. The socket 15 is provided intermediate its ends with a plurality of pockets 16 which pockets receive the lug 6 previously described. The inner end of the auxiliary section is threaded so as to engage the threads of the collar 7 *wherby the primary and auxiliary sections may be firmly clamped together. A packing 17 is positioned within the socket. 15 and rests against the flange 5 of the primary section. This packing is firmly clamped upon its primary section through the collar 7.

In view tion 10 is provided with a number of pockets 16 it is not necessary for the-primary section to be placed at any definite position as the primary section may be placed within the auxiliary section withoutany great care and slightly rotated until the lug '6 comes in contact with one of the pockets 16., The collar 7 is then threaded within the auxiltightly holding the primary and auxiliary sections together.

Having thus described the invention, what I claim is:

A coupler of the class described com-' prising a primary section, and an auxiliary section, said primary section being provided with a plurality of angesformed thereon, a collar slidably mounted upon said primary section between said flanges, said flanges being adapted to limit the movement of sai collar upon said primary section, said auxiliary section being provided with a plu- The auxiliary sect-ion is also medium of the of the fact that the auxiliary seccollar being provided with areduced threaded portion, said auxiliary section being procollar being adapted to clamp said packing 10 vided With an enlarged threaded portion firmly against said flange of said primary adapted to receive said threaded portion of section.
